Steel C-channel is a popular support option for dining tables, desks, conference tables, workbenches, and other custom furniture projects made from solid wood.\n    \u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv style=\"margin-bottom: 18px;\"\u003e\n    \u003ch3 style=\"font-size: 20px; margin: 0 0 8px;\"\u003eDoes C-channel stop wood movement?\u003c\/h3\u003e\n    \u003cp style=\"margin: 0;\"\u003e\n      No. C-channel adds support and stiffness, but solid wood will still expand and contract with humidity changes. It should be installed in a way that supports the top without locking the wood in place too aggressively.\n    \u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv style=\"margin-bottom: 18px;\"\u003e\n    \u003ch3 style=\"font-size: 20px; margin: 0 0 8px;\"\u003eHow do I know if my top needs C-channel?\u003c\/h3\u003e\n    \u003cp style=\"margin: 0;\"\u003e\n      Wider tops, large slabs, long desks, and bigger glued-up panels often benefit from extra reinforcement. If the table top is large, heavy, or needs added underside stiffness, C-channel is worth considering.\n    \u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv style=\"margin-bottom: 18px;\"\u003e\n    \u003ch3 style=\"font-size: 20px; margin: 0 0 8px;\"\u003eHow many C-channels should I use?\u003c\/h3\u003e\n    \u003cp style=\"margin: 0;\"\u003e\n      The number depends on the size of the top, the width of the panel, the thickness of the wood, and the base design.

This is commonly done with a router before the table is finished.\n    \u003c\/p\u003e\n  \u003c\/div\u003e\n\n\n","brand":"Jeff Mack Supply","offers":[{"title":"20\" Black C-Channel","offer_id":45052154872005,"sku":"20-C-Channel","price":29.0,"currency_code":"CAD","in_stock":true},{"title":"31\" Black C-Channel","offer_id":45052154904773,"sku":"31-C-Channel","price":39.0,"currency_code":"CAD","in_stock":true},{"title":"36\" Black C-Channel","offer_id":45052154937541,"sku":"36-C-Channel","price":44.0,"currency_code":"CAD","in_stock":true},{"title":"42\" Black C-Channel","offer_id":45052154970309,"sku":"42-C-Channel","price":49.0,"currency_code":"CAD","in_stock":true},{"title":"M6 Threaded Insert","offer_id":45052167717061,"sku":"RMPA-SK-M6","price":0.99,"currency_code":"CAD","in_stock":true},{"title":"M6 Bolt (Black 25mm)","offer_id":45456611901637,"sku":"KF-M6-25mm-BLACK","price":0.4,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0054\/3824\/2883\/files\/steel_c-channel_table_top_support.jpg?v=1775500794"}],"url":"https:\/\/jeffmacksupply.com\/collections\/c-channel\/category_accessories.oembed","provider":"Jeff Mack Supply","version":"1.0","type":"link"}
